Staphylococcus aureus infection elicits antibodies against wall teichoic acid (WTA). Several glycosyltransferases modify WTA to generate anomeric heterogeneity. In recent work, Gerlach et al. (2018) show that modification by prophage-encoded TarP diminishes WTA immunogenicity, allowing staphylococci to evade host adaptive immune responses, and propose to exploit these insights for vaccines.
金黄色葡萄球菌感染会引发针对壁磷壁酸(WTA)的抗体。几种糖基转移酶修饰 WTA 以产生端基异构性。在最近的研究中,Gerlach 等人(2018 年)表明,噬菌体编码的 TarP 的修饰会降低 WTA 的免疫原性,使葡萄球菌能够逃避宿主适应性免疫反应,并提议利用这些见解开发疫苗。
